I've been enjoying using the new dynamic tool paths in MX9. From what I gather, the idea is to use a % of tool dia. as radial depth of cut (ie: 10% for step over), using a standard carbide tool (usually bull mill) and have a large depth of cut axially. (usually flute length of tool or pocket depth) I've heard this style of cutting called, "Radial Chip Thinning." I've been experimenting with different radial (max.) depth of cut/feed/speeds. I would like to do better than guess. However most of the "chip thinning" calculators seem to be based on axial chip thinning. (ie: small axial depth of cut and fast feed rates.) I tried the Iscar chip thinning calculator referred to in a previous post and it won't let me enter an axial depth of cut larger than the bull mill radius. Can any one point me in the right direction as far as speeds/feeds for these new dynamic tool paths?

Hello Guys, I'm machining a 1.25 wide slot 4.5 deep using a 1.0 high feed cutter. The first part of cutting the slot is full diameter of the tool but on the way back the radial depth of cut is .25 so I use the chip thinning formula and my increased my feed. The question I have is how do I get Mastercam to post that out, I don't want to manually go into the program and change the feed for every depth cut. I played with the High feed settings in Mastercam but I'm not getting the desired results, but it could be that I'm not using correct settings. Any ideas? TIA, Greg
